I'm very happy to tell you that Sonnet Software maintains our commitment to students and learners through free access to top-notch high frequency electromagnetic (EM) software. On behalf of my colleagues at Sonnet, I would like to welcome you to the latest edition of our well-known Sonnet Lite software for high frequency 3D planar electromagnetic analysis:

SONNETR Lite Release 12.

Release 12 represents our sixth full release of Sonnet Lite over the past decade. We're proud to provide a leading-edge "virtual prototyping" tool for the student and experimenter in high frequency planar circuits, packages and antennas.

Variables for Material Properties and Thicknesses: You can now assign project variables to control dielectric thickness, dielectric loss properties, metal thickness and loss properties, and Ideal Component (SMD L,R,C) values. These variables can also be used for parameter sweep analysis and optimization (optimization in Sonnet LitePlus only).

Equation-Based Variables: Geometry and property controls may now be expressed as functions of variables, math functions, and other geometry parameters.

Radial Dimension Parameters: A new geometry parameter type has been added to control the radial dimensions of rounded features. A useful control for fan stubs, circles, and the radius of curved transmission line bends.

Enhanced Meshing Engine: Our default meshing engine has increased efficiency, doing the same job with less subsections, less memory and less time. Somewhat larger problems can now be solved.

Hot Key Mapping: Create your own key bindings for the things you do most often, or make bindings that are similar to other CAD tools that you use. Hot key bindings may be made for the Sonnet Project Editor, Response Viewer and the Current Density Viewer.

Append Feature for the DXF Translator: For Sonnet LitePlus users only. You can now import multiple independent DXF files into the same Sonnet Project.

Don't' forget that Sonnet Lite Version 12 can be fully integrated within the AWR Microwave Office or Agilent ADS environments. We continue to provide our seamless integration capability for these RF design flows, free of charge for Sonnet Lite and Sonnet LitePlus. Check out videos with integration demonstrations:

Sonnet LitePlus users please note: There is an upgrade charge of $150 per version to change versions. Please contact your Sonnet Technical Sales representative for more details.

--> Special Note to IEEE MTT-S / IMS 2009 Attendees: Visit Sonnet Software's booth (#1002), take a 20-minute class in using Sonnet Lite, and get a Sonnet LitePlus upgrade at NO COST. Classes are offered in our booth, and no reservation is required. For details, please visit:

Thank you for using Sonnet Lite in the past. We hope you'll continue to enjoy our software as a tool for learning and experimenting in the high frequency RF domain. And if you are ever in need of an upgrade to your Sonnet Lite or LitePlus, please contact us.
